[keltro]

I purchased a 0-540 engine mount ring (only) from "VANS" for their RV-10........Be advised that it is for a 0-540 with the "30" degree mount ears (Part # 70456) with a 1.385 inch center mount hole used on the following engines......D4A5,G1D5,K1A5,K1A5D,K1B5,K1D5,K1E5,K 1G5,K1G5D,T4A5D,T4B5D.........I would
ask "VANS" what size tubes are used on their RV-10 mount from firewall to the mount ring..........
